Abstract (en)

[origin: CA2837001A1] The present invention relates to a lubricant composition comprising at least one polyalkyl (meth)acrylate, comprising repeating units derived from (meth)acrylates having 6 to 22 carbon atoms in the alcohol residue, the polyalkyl (meth)acrylate comprising repeating units derived from ethylenically unsaturated monomers having at least one covalently bonded phosphorus atom. The present invention further describes a polyalkyl (meth)acrylate which is suitable for a lubricant composition of this kind, and also describes the use of a polyalkyl (meth)acrylate having repeating units derived from ethylenically unsaturated monomers having at least one covalently bonded phosphorus atom, for the purpose of reducing friction.
